So DD is 16 weeks. She's been in her crib since 5 weeks and sleeping through the night since 9 weeks. Then around 13 or 14 weeks she wakes constantly. Not to eat or anything she just wakes up. Some nights she'll still sleep through but it's sporadic. She has eczema and started teething around 14 weeks ( I teeth have cut through yet) so I'm not sure if that bothers her sometimes and disturbs her sleep. All I know is I've tried everything and nothing seems to work. I've heard of sleep regression in babies around during 6 or 7 months so maybe that could be happening. Has anyone else experienced something similar or have any tips for me? I'm losing my mind.
